The Wesnoth Units Database, accessible at units.wesnoth.org, provides a way to view all information, such as name, advancement path, terrain movement costs, etc, about mainline and add-on units via a browser.

These web pages are automatically generated via a script that runs weekly. If for some reason units.wesnoth.org is inaccessible, or any of the unit information has not been updated in over a week, or if you have any questions in general about the units database, please post those here.

1. Please do not use colors when posting.
2. Please do not post the same thing in multiple places. As such, I have deleted your thread in the WML Workshop, since that is not the place for questions about why units.wesnoth.org is displaying an error.

As far as your problem, I can't say for certain, but I would guess that it has to do with me getting the following text written to the error log when I load Wesnoth after installing Chalifa:

If you have any additional questions about the warnings/errors that Wesnoth is displaying in the log, then the WML Workshop would be the place to ask about them.

and refuses to continue. The said macro is defined in core, more specifically in data/core/macros/utils.cfg. Can anything be done about it? (And btw, it reports version v1.13.6+dev even though it is from 1.12.)

I'll see if I can get a better answer for why it's using 1.13.6 on the 1.12 units database. In the mean time though, your campaign uses image paths from the "transparent" folder, which no longer exists and creates a few errors in the error log:

@Ravana Sure. Maybe there are ways to tell the script/parser about the macro's existence. Because I would prefer to keep this line: {VARIABLE enemies_to_spawn {ON_DIFFICULTY 1 2 2}}. Of course, I know a workaround.
@Pentarctagon Well, in master on GitHub I already use correct paths for Wesnoth 1.13, like this: https://github.com/konecnyjakub/For_Pow ... in.cfg#L35. The thing is that I just did not release a new version in a long time.

The problem was that units.wesnoth.org only understood the difficulties=EASY,NORMAL,HARD syntax but would ignore [difficulty] elements. I just updated it to define the very first [difficulty] it finds, so ON_DIFFICULTY works now.

Thank you but are you sure about it working now? Because that error was happening on both 1.12 and master. Well, we will see in a week anyway. Edit: Well, probably forget it. The 1.12 version was using master actually.

The way it is setup is that the master version of the "wmlunits" script is always used. (Mainly because I got tired of having to backport the script changes to 1.12.) But 1.12 will use the 1.12 wesnoth binary to do the WML parsing while master will use the master binary. So yes, the [difficulty] change will also benefit the 1.12 campaigns on the addon server.
